Based on the above problem, the embodiment of the present application provides an anti-theft alarm system as shown in fig. 1: an input device 10 for outputting a target protected object recognition signal and an operation mode selection signal; the sensors 20 are used for outputting detection signals, and the detection signals are used for representing whether the protected object corresponding to the sensors 20 is stolen; the switch modules 30 are used for being correspondingly connected with the power supply modules 50 one by one, and the switch modules 30 are also correspondingly connected with the sensors 20 corresponding to the protected objects one by one; the controller 40, each controller 40 and each switch module 30 and each sensor 20 are uniformly and correspondingly connected, each controller 40 is connected with the input device 10 in a remote communication way, the controller 40 is used for controlling the switch module 30 correspondingly connected with the controller 40 to be switched on or switched off according to the working mode selection signal when the corresponding protected object is judged to be the target protected object according to the target protected object identification signal, and outputting an alarm signal according to the received detection signal when the switch module 30 is switched on; and the communication module 60 is correspondingly connected with the controller 40 in a communication manner, and the communication module 60 is further used for connecting the terminal 70 and obtaining and sending alarm information to the terminal 70 according to the alarm signal.
The target protection object refers to an object which a user wants to control in a arming or disarming state. The input device 10 may be a terminal 70 such as a mobile phone integrated with APP, or may be a signal generator having a handwriting screen or a control key, and may generate a target protected object identification signal and a working mode selection signal according to content input by a user on the handwriting screen or a specific action of the user operating the control key. The target protected object identification signal is a signal for identifying whether or not the protected object corresponding to the controller 40 is the target protected object. The operation mode selection signal is a signal for indicating that a control system (a small system including the controller 40, the sensor 20, the switch module 30, and the communication module 60) corresponding to the target protected object is in the arming operation mode or the disarming operation mode. The switch module 30 may be an electronic switch, a relay switch, or the like type of switch. The power module 50 may be a direct power supply or a power adapter, one end of which is connected to the commercial power and the other end of which outputs the working voltage of the sensing module, the controller 40 and other hardware modules. The controller 40 is a device capable of implementing functions of signal reception, signal processing, and alarm signal transmission, and may be, for example, a single chip microcomputer, the embedded controller 40, a PLC, or the like. The sensor 20 refers to a device capable of collecting a signal indicating whether the protected object is stolen, and the sensor 20 is often disposed near the protected object or at the boundary of the area where the protected object is located.

The alarm information can comprise an alarm state, information of a protected object in which the theft danger occurs and the like, and is used for reminding a user of which the protected object is in the theft danger, so that the user can alarm or perform other processing. The corresponding connection between the controller 40 and the communication module 60 may be that a plurality of controllers 40 are correspondingly connected to a plurality of communication modules 60, for example, the controllers 40 corresponding to houses and garages are relatively close to each other, and may share one communication module 60. Or the controller 40 itself may have a communication function, and may perform wireless communication with the communication module 60 within a certain range. The controllers 40 and the communication modules 60 may also be connected in a one-to-one correspondence, and for the case where the two application scenarios, garage and vehicle, may be far apart, the independent controller 40 corresponds to the independent communication module 60.
Specifically, when a user has two or more objects to be protected, for example, a plurality of objects such as vehicles, garages, houses, etc. need to be monitored for theft prevention. To better explain the working principle of the burglar alarm system provided in the embodiment of the present application, the following examples are provided to illustrate that the burglar alarm system is not only suitable for the following situations, but also suitable for other application scenarios. When a user leaves home, the anti-theft monitoring of a garage and a house needs to be started, at this time, the user can operate the input device 10, then the device outputs a target protected object identification signal and a working mode selection signal to each controller 40, each controller 40 works under the power supply of the power supply module 50, and then each controller 40 judges whether a protected object corresponding to the controller 40 is a target protected object according to the target protected object identification signal. The judgment implementation process may be: each protected object has a unique number (the garage is 1, the house is 2), the target protected object identification signal carries the number (which may be one or more numbers, for example, 1 and 2) of the protected object that the user wants to control, the controller 40 analyzes the number to obtain the number in the target protected object identification signal, and compares the number with the number of the corresponding protected object pre-stored in the controller 40 (the number pre-stored in the controller 40 corresponding to the garage is 1, and the number pre-stored in the controller 40 corresponding to the house is 2), if the numbers are equal, the protected object corresponding to the controller 40 is the target protected object. Since the user leaves home, the anti-theft monitoring of the garage and the house needs to be started (the identification signal of the target protected object carries the numbers 1 and 2, and the working mode selection signal is used for indicating that the corresponding protected object is in the defense state), the controller 40 corresponding to the garage and the house controls the corresponding switch module 30 to be closed according to the working mode selection signal, the power supply circuit of the power module 50 and the sensor 20 is switched on, the sensor 20 detects the environment around the garage and the house and outputs the detection signal to the corresponding controller 40, the controller 40 judges whether the danger of theft happens around the garage and the house according to the detection signal, if the danger of theft happens, the alarm signal is sent to the communication module 60 and converted by the communication module 60 and sent to the terminal 70 in the form of communication information for display, and the user can see whether the danger happens to the garage or the house at the terminal 70, so as to carry out the next operation and recover the property loss.
When a user goes out, the control system corresponding to the garage and the house is set to be in a defense deployment working mode, at this time, if the user visits relatives and friends and requires the user to have a rest indoors, the user can enable the input device 10 to output a target protected object identification signal (which can be a signal carrying the house number 2) and a working mode selection signal used for indicating defense withdrawal, after the controller 40 corresponding to the house receives the identification signal, the controller 40 controls the switch module 30 corresponding to the house to be disconnected according to the working mode selection signal, at this time, the sensor 20 is in a power-off non-working state, namely, the anti-theft monitoring corresponding to the house is failed, the relatives and friends of the user can open the house door and enter the house to wait for the user to return, and the anti-theft alarm system cannot give an alarm in the process.
In the burglar alarm system provided in the embodiment of the present application, each controller 40 identifies whether it is a arming operation mode selection signal issued to a protection object corresponding to the controller 40 by determining a target protection object identification signal and an operation mode selection signal output by the input device 10, and if so, controls the switch module 30 to be turned on or off according to the operation mode selection signal to implement arming or disarming, in the arming mode, the controller 40 determines whether a dangerous theft situation occurs according to a detection signal transmitted by the sensor 20, and when determining that the dangerous situation occurs, may send an alarm signal to the corresponding communication module 60, and after protocol conversion by the communication module 60, convert the alarm signal into an alarm message to the terminal 70, so that a user monitors the security state of the target protection object at the terminal 70. The anti-theft alarm system provided by the embodiment of the application can realize anti-theft monitoring on the protected objects of a plurality of application scenes without carrying a plurality of controllers 40, and is convenient to use.
In one embodiment, as shown in fig. 2, the detection signal includes a first electrical signal and a second electrical signal, and each sensor 20 includes: the biological sensing module 21 is used for being connected with the power supply module 50 and outputting a first electric signal, and the first electric signal is used for indicating the temperature of an object around the protected object; the door magnetic device 22 is used for connecting the power supply module 50, the door magnetic device 22 is arranged on a door and a window of a protected object and is used for outputting a second electric signal when the door and the window are detected to be opened; the controller 40 is in communication connection with the bio-sensing module 21 and the door magnet device 22, respectively, and is configured to output an alarm signal according to the received first electrical signal and second electrical signal when the switch module 30 is closed.
The biological sensing module 21 may be a module for detecting parameters such as temperature of an object around the protected object, and the biological sensing modules 21 of different models have different detection ranges, for example, the detection range of the biological sensing module 21 may be 10-80cm, or 8 m. The first electrical signal V1 indicates the temperature of the object within the detection range of the bio-sensing module 21. The door magnet device 22 is a device for a security alarm to detect whether a door, a window, etc. is illegally opened or moved. The alarm information is information capable of reminding a user of the risk of theft of a protected object in a defense state. Both the bio-sensor module 21 and the door magnet device 22 operate when the switch module 30 to which they are connected is closed.
Specifically, when the switch module 30 is closed, the controller 40 corresponding to the switch module 30 continuously receives the first electrical signal V1 sent by the biological sensing module 21, and when it is determined that the surrounding object is a living being (e.g., a person) according to the first electrical signal V1, if the controller 40 receives the second electrical signal V2 again, it indicates that a living being attempts to illegally open the door and window of the protected object, at this time, the controller 40 sends an alarm signal to the communication module 60, the communication module 60 converts the alarm signal into an alarm message to the terminal 70, and the alarm message is displayed on the terminal 70 to remind the user that the current protected object is stolen, so that the user can perform subsequent operations, and property loss is avoided.
In one embodiment, the communication module 60 is a GSM (Global System for Mobile Communications) module. The GSM module integrates a GSM radio frequency chip, a baseband processing chip, a memory, a power amplifier device and the like on a circuit board, and is a functional module which is provided with an independent operating system, GSM radio frequency processing and baseband processing and provides a standard interface. The GSM module can be used for monitoring at an infinite distance within 24 hours, and the GSM module is used for communication, so that the anti-theft alarm system in the embodiment of the application can be free from distance limitation. The GSM Module may be provided with a SIM card (Subscriber identity Module), which is also called a Subscriber Identity Module (SIM) card or a smart card. When the controller 40 determines that the surrounding object is a living being (e.g., a person) according to the first electrical signal V1, if the controller 40 receives the second electrical signal V2 again, it indicates that the living being tries to illegally open the door and window of the protected object, at this time, the controller 40 sends an alarm signal to the GSM module, the GSM module converts the alarm signal into alarm information to the terminal 70, and the GSM module sends the alarm information to the terminal 70 in the form of short message, call, WeChat, QQ message, etc. to remind the dangerous situation. The GSM module can adopt a Siemens TC35I chip or other types. The biological sensing module 21 may be an infrared temperature sensor 2122012 array MLX90621 (including other single-point and array sensors 20) of MELEXIS, and the temperature detection is realized by using an infrared thermopile principle, and a thermopile hot junction senses the temperature difference between the environment and the temperature of the object according to the infrared radiation of the object and converts the temperature difference into a voltage signal.
According to the anti-theft alarm system provided by the embodiment of the application, due to the adoption of double sensing detection, false alarm caused by collision of non-biological objects such as stones and bicycles with protected objects due to wind power or other factors is eliminated, and the alarm reliability is greatly improved.
In one embodiment, as shown in fig. 3, the bio-sensing module 21 includes: an infrared sensor 2112011 for measuring the integrated temperature in the environment of objects surrounding the protected object; a temperature sensor 2122012 for measuring ambient temperature; a logic operator 21313, a first input terminal of the logic operator 21313 is connected with the infrared sensor 2112011, a second input terminal of the logic operator 21313 is connected with the temperature sensor 2122012, and the logic operator 21313 is used for calculating the temperature difference value between the ambient temperature and the comprehensive temperature; the electrical signal conversion module 21414 is configured to convert the temperature difference into a first electrical signal V1.
The integrated temperature refers to the temperature of an object in the environment within the detection range of the infrared sensor 2112011, and this temperature is affected by the ambient temperature. The ambient temperature is the temperature of the environment such as the air around the infrared sensor 2112011. The logic operator 21313 receives the integrated temperature detected by the infrared sensor 2112011 and the ambient temperature measured by the temperature sensor 2122012, performs difference operation on the integrated temperature and the ambient temperature, removes the influence of the ambient temperature on the temperature of the object, obtains a temperature difference value capable of reflecting the actual temperature of the object, transmits the temperature difference value to the electrical signal conversion module 21414, and converts the temperature difference value into a first electrical signal V1 through the electrical signal conversion module 21414, so that the controller 40 determines whether the object around the protected object is a living being according to the first electrical signal V1.
In one embodiment, as shown in fig. 4, the first electrical signal V1 is a voltage signal, the second electrical signal V2 is a high-level voltage signal, and the controller 40 includes: the first end of the voltage comparator 4131 is used for receiving a first electric signal V1, the second end of the voltage comparator 4131 is used for receiving a first reference voltage signal C1, the output end of the voltage comparator 4131 outputs a comparison result signal, and when the first electric signal V1 is greater than the first reference voltage signal C1, the comparison result signal is a high-level voltage signal; and the first end of the and logic operator 4232 is used for accessing the comparison result signal, and the second end of the and logic operator 4232 is used for accessing the second electric signal V2 and outputting an alarm signal when the and logic operation result is a high-level voltage signal.
The first reference voltage signal C1 is the lowest voltage that can determine that the surrounding object is a living being. The specific structure of the controller 40 may be composed of a voltage comparator 4131 and an and logic operator 4232.
